Motech plans to increase annual capacity to 1.8 gigawatts by the end of next year, from 1.2 gigawatts now, after orders exceeded production, chief executive officer Chang Ping-heng (張秉衡) said on Wednesday in an interview in Taipei. The solar cell maker is in talks for a loan to help pay for an expansion, he said, declining to give details.

Global installations of solar panels may more than double to 15.8 gigawatts this year as developers seek to set up systems and benefit from government incentives, technology researcher Isuppli said. Demand may rise to 19.3 gigawatts next year, Isuppli said last month.

“With the large volumes, Motech has an advantage in cutting prices to compete,” said Johnson Lin, a Taipei-based analyst at Capital Securities Corp (群益證券) who has a “neutral” rating on the solar industry.

Solar panel sales to the US, Canada and Japan are rising, Chang said. Europe, the US and Asia each account for one-third of the company’s revenue, he said.

“Demand is so strong this year that we aren’t able to fully -supply our customers,” said Chang, a former vice president of Taiwan Semiconductor Manufacturing Co (TSMC, 台積電), the world’s largest contract maker of chips. “Our capacity for next year has all been committed out.”

Motech expects to use its full production capacity next year, even as a worldwide glut of panels may develop, because the company expects to overcome the threat of oversupply, he said. Global annual capacity to produce solar cells may climb to as much as 30 gigawatts, Chang said, exceeding Isuppli’s demand projection by about 55 percent.

“There’ll be an overcapacity next year,” Chang said. “That’ll create pressure for newcomers.”

Recent entrants to the solar panel market will need time to certify products and improve yields, he said.

“The real good customers won’t immediately place orders to these companies,” he said.

Motech also produces solar modules and silicon wafers for manufacturing cells. TSMC is Taipei-based Motech’s largest shareholder, with a 20 percent stake.

Motech expects sales and profit next year to increase from this year, buoyed by an expansion in capacity and rising demand for solar panels, Chang said, declining to give numbers.

Chang said earnings would improve even as solar cell prices may decline 10 to 15 percent next year as falling subsidies in some European countries prompt customers to ask for a drop in charges.

“It’s reasonable for solar system makers to cut prices by 20 to 25 percent, to stimulate end demand, and then sales will increase,” Lin said.

Spain last month reduced subsidies for new solar-power projects. Solar-panel installations on home roofs will be paid 5 percent less than previously, the government said on Nov. 19.

The company had net income of NT$3 billion (US$99 million) in the first nine months of the year, compared with a loss of NT$334 million a year earlier, the company said in a statement on Oct. 28. Sales almost doubled to NT$20.3 billion.
